How can I display an image in the terminal?

问题

Is there any sort of utility I can use to convert an image to ASCII and then print it in my terminal? I looked for one but couldn't seem to find any.

回答1:

A program called cacaview allows you to do this.

It is interactive, allowing you to pan, zoom, and change display modes.

Try using the Google-Ninja before asking! I found cacaview and aview.

回答3:

more simply, you may use img2txt from the caca library (cacaview is an image browser and opens a new window, which is not what is asked here I guess);

For instance :

$ img2txt /Users/foo/pool/libs/ipython/docs/resources/ipynb_icon_256x256.png

on macosx, you may use homebrew :

$ brew reinstall libcaca --with-imlib2

(imlib is used to convert from different formats)

Here's a utility that does this (with source code):

A high quality fast standalone conversion utility (provided you have a 256 color terminal) is pxl, available at https://github.com/ichinaski/pxl.

回答6:

Another alternative is to use the Ipython notebook: it is pretty good at doing what you ask for.

For bash: You have to prepend commands with a bang. For images: You may use the rich display system from ipython.
